in the world with such a big flock. and as i say, who else rules a billion people other than the heads of china and india? >> a major, major news event for catholics and non-catholics alike. thanks very much. so, cynthia, tomorrow is the departure of benedict xvi, and then begins the discussions about who comes next. we'll be here. back to you. >> and our thanks to you, terry, and christiane. it's time now for our closing arguments. it's a case of wild airport rage caught on tape. a chinese official kicking walls and throwing computers at an airline check-in counter. while his temper tantrum is extreme, many can sympathize with his frustration. but is blowing your lid like this ever justified? you can weigh in on "nightline's" facebook page or tweet us. thank you for watching abc news. good night, america.
